Warning signs in its filings
Problems the company itself reported to the SEC, in its own words.
2 serious warning signs in Neuraxis’ filings.
We look for five warning signs: doubt it can keep going, weak checks on its own accounts, a notice that its past accounts can't be relied on, a change of auditor, and one customer bringing in a big share of sales. We don't check lawsuits, investigations or debt yet.
We checked the auditor's report, internal controls, restatement notices, auditor changes and big customers in the 10-K filed 19 Mar 2026, plus the 10-Q filed 11 Aug 2026 and 5 later 8-Ks.
Doubt it can keep going
SeriousThe company or its auditor warned it may not have enough money to last the next year.
“As a result, substantial doubt is deemed to exist about the Company’s ability to continue as a going concern.”
Show the full paragraph
While the Company believes in the viability of its strategy to further implement its business plan and generate sufficient revenues and in its ability to raise additional funds by way of a public or private offering of its debt or equity securities, there can be no assurance that it will be able to do so on reasonable terms, or at all. The ability of the Company to continue as a going concern is dependent upon its ability to further implement its business plan and generate sufficient revenues and its ability to raise additional funds by way of a public or private offering. Neither future cash generated from operating activities, nor management’s contingency plans to mitigate the risk and extend cash resources through the evaluation period, are considered probable. As a result, substantial doubt is deemed to exist about the Company’s ability to continue as a going concern. As the Company continues to incur losses, the transition to profitability is dependent upon achieving a level of revenues adequate to support its cost structure. We may never achieve profitability, and unless and until doing so, we intend to fund future operations through additional dilutive or nondilutive financing. There can be no assurances, however, that additional funding will be available on terms acceptable to us, if at all.

Weak checks on its own accounts
SeriousThe company said its checks on its own accounts did not work at the end of its latest quarter. Mistakes could slip into the numbers.
“Based on this evaluation, and in light of the material weaknesses in our internal control over financial reporting described below, our principal executive officer and principal financial officer concluded that as of June 30, 2026, our disclosure controls and procedures were not effective.”
Show the full paragraph
We maintain “disclosure controls and procedures,” as that term is defined in Rule 13a-15(e), promulgated by the SEC pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our Company’s reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer to allow timely decisions regarding required disclosure. Our management, with the participation of our principal executive officer and principal financial officer, evaluated our Company’s disclosure controls and procedures as of the end of the period covered by this Form 10-Q. Based on this evaluation, and in light of the material weaknesses in our internal control over financial reporting described below, our principal executive officer and principal financial officer concluded that as of June 30, 2026, our disclosure controls and procedures were not effective.

A 10-K is the yearly report every US company files with the SEC. An 8-K is a short notice of a big event.
